Impact of a Historical Fire Event on Pyrogenic Carbon Stocks and Dissolved Pyrogenic Carbon in Spodosols in Northern Michigan
Inventories of fire-derived (pyrogenic) C (PyC) stocks in soils remain incomplete for many parts of the world, yet are critical to reduce uncertainties in global PyC estimates. Additionally, PyC dynamics in soils remain poorly understood. For example, dissolved PyC (DPyC) fluxes from soil horizons, as well as the influence of historical fire events on these fluxes and soil PyC stocks remain poo...
متن کاملTrial by Fire: On the Terminology and Methods Used in Pyrogenic Organic Carbon Research
Our understanding of the cycling of fire-derived, i.e., pyrogenic organic matter (pyOM), as well as the goals of the community of researchers who study it, may be inhibited by the many terms and methods currently used in its quantification and characterization. Terms currently used for pyOM have evolved by convention, but are often poorly defined. Further, each of the different methods now used...
متن کاملPyrogenic organic matter production from wildfires: a missing sink in the global carbon cycle
Wildfires release substantial quantities of carbon (C) into the atmosphere but they also convert part of the burnt biomass into pyrogenic organic matter (PyOM). This is richer in C and, overall, more resistant to environmental degradation than the original biomass, and, therefore, PyOM production is an efficient mechanism for C sequestration. The magnitude of this C sink, however, remains poorl...
متن کاملTowards a global assessment of pyrogenic carbon from vegetation fires.
The production of pyrogenic carbon (PyC; a continuum of organic carbon (C) ranging from partially charred biomass and charcoal to soot) is a widely acknowledged C sink, with the latest estimates indicating that ~50% of the PyC produced by vegetation fires potentially sequesters C over centuries. Nevertheless, the quantitative importance of PyC in the global C balance remains contentious, and th...
متن کاملGround based sampling of pyrogenic emissions from Big Elk Fire, Estes Park, CO
In order to fully understand the impact of pyrogenic emissions it is necessary to have a good understanding of the microphysics of clouds. Cloud formation and the aerosol emissions from wildfires are intimately connected. By understanding these interactions it is possible to investigate the role aerosols play in precipitation processes and the radiation budget. Of extreme importance are the aer...
